Increasing prevalence of myopia, particularly in Asian urban children, confirms that life style in childhood and infancy may play a role (3). Today potential effect of early life nutrition on myopia development in later life is becoming an attractive field of study. Breastfeeding has been related to neural development which affects visual acuity. Up to weaning, breastfeeding is the main source of many micronutrients [including docosahexanoic acid (DHA)], which are important for light receptors and brain neural development (6). A study which was done in Singapore showed that breastfeeding is independently related to likelihood of myopia after controlling for cofactors (7). But this study had some limitations which may affect the results. This study had a small population size and its participants were from one school. All factors relating to myopia were not controlled by this study. However, data pulled from three English birth cohorts done in 10-11y and 15-16y children did not show any effect (8). Hence, results about the relationship between breastfeeding and likelihood of childhood myopia are controversial.
